The NMS inventory module 42, the NMS southbound module 43, and the EMS inventory module 44 can be understood with reference to the prior art.

For example, the NMS inventory module 42 is set in the NMS system to manage inventory information such as network elements, subracks, boards, ports, optical fibers, and subnets. This information can be stored in an inventory database.

The EMS inventory module 44 is set in the EMS system to manage inventory information such as network elements, subracks, boards, ports, optical fibers, and subnets.

Next, with reference to FIG. 4 and FIG. 5, the network element management method of the embodiment of the present invention is described, including:

51. The NMS inventory module sends a request to the network element management module to query the splicing strategy.

As shown in Figure 6, the NMS manages two EMSs, EMS-1 and EMS-2. After the NMS uploads the EMS information, there will be network boundary points between EMS-1 and EMS-2 (that is, there are duplicate network elements).

The NMS inventory module sends a request to the network element management module to query the splicing strategy. The request may carry network element IDs of all network elements in EMS-1 and EMS-2.

52. The network element management module queries the network element data from the stock database.

53. The network element management module obtains the query result from the stock database.

54. After the network element management module obtains the query result from the stock database, it starts to calculate the network element management result according to the network element management policy.

The query results of network element data are shown in Table 1:

Among them: the network element ID is the unique ID allocated for each EMS network element on the NMS, and is generally allocated in order. Here, in order to stagger, the values from 1000 and later are used sequentially for EMS-1, and the values from 2000 and later are used sequentially for EMS-2.

The network element serial ID is a globally unique ID assigned when the equipment leaves the factory, including but not limited to the equipment of a certain equipment supplier.

Start calculating the network element management results according to the network element management policy, which may include:

(1) A group of network elements with the same network element flow ID (such as in Table 1: network element 1 and network element 1') is called a "fusion group", one of which is the main network element, and the others are backup networks Yuan. Whether the active NE or the standby NE depends on the implemented algorithm. In this example, the one with the smallest NE ID is the active NE, and the others are the standby NEs. Because the NE ID of NE 1 in Table 1 is smaller than that of NE 1', NE 1 is the primary NE, and NE 1' is the backup NE.

(2) In the fusion group, only the first one (the one with the smallest NE ID) is kept, and the other NEs are deleted and put into the list of deleted NEs.

(3) As shown in Table 1, NE 1', NE 2', and NE 3' are duplicate NEs, delete them, and put NE 1', NE 2', and 3' into Deleted NE list.

55. The network element management module queries the fiber and cable data from the inventory database.

56. The network element management module obtains the query result from the stock database.

57. After obtaining the query result, the network element management module starts to calculate the fiber and cable management result according to the fiber and cable management strategy.

The fiber and cable data query results are shown in Table 2:

Among them, the fiber and cable serial number is the unique ID allocated for each fiber and cable on the NMS, and is allocated in sequence.

Moreover, according to the above step 52, it can be known that the network element 1', the network element 2', and the network element 3' are repeated network elements, which have been put into the list of deleted network elements.

Start calculating fiber and cable management results according to the fiber and cable management strategy, including:

(1) Both the source-end NE and the sink-end NE are in the “deleted network element list” (such as in Table 2: fiber 4, fiber 5, fiber 6), directly delete the fiber .

(2) If neither the source-end network element nor the sink-end network element is in the "deleted network element list" (such as in Table 2: fiber cable 1, fiber cable 2, fiber cable 3), keep the fiber cable, No change.

(3) For the fiber and cable in the "deleted network element list" (such as fiber cable 7 and fiber cable 8 in Table 2) on the side of the source network element or sink network element, delete the fiber cable. Then create a new NMS fiber cable. One end of the newly created fiber cable is the end of the original fiber cable that is not in the "Deleted NE List". The other end of the newly created fiber cable is the original fiber cable in the "Deleted NE List". The corresponding position of the main network element in the fusion group corresponding to the network element.

For example: the source end of fiber cable 7 is NE 2'-1-1, and the sink end is NE 4-1-1, so fiber cable 7 is deleted, and then a new NMS fiber cable 7' is created, and the source end is network element 4-1-1. element 2-1-1, and the sink end is network element 4-1-1.

Among them, NMS fiber and cable 7' and NMS fiber and cable 8' are NMS-level cables created by the NMS according to the fiber and cable management strategy, and the IDs are also uniformly allocated by the NMS. Here, the allocation is 100 and 101 for example.

58. The network element management module returns the network element management result and the fiber and cable management result to the NMS inventory module.

The network element management results are shown in Table 3 below:

The fiber and cable management results are shown in Table 4 below:

59. The NMS inventory module splices the network according to the network element management results and fiber cable management results, deletes duplicate network elements, fiber cables, and establishes cross-EMS fiber cables to form a complete network.

The NMS inventory module splices the network according to Table 3 and Table 4, deletes duplicate network elements, fibers and cables, and establishes cross-EMS fibers and cables to form a complete network. As shown in Figure 7, a complete network is formed after final splicing.

The NMS inventory module can also modify the data in the inventory database.
